proveniente in ShocloAcbsoi-bers, of which the following' is e.specitioation.

This invention relates to' certain improve ments in shock absorberswhich are primarily etlapted 'for use 'upon enclin connection with motor(iiive'n and other vehicles; ancl its essential object is to produce adevice having its various parte so constructed, conibined, and arrangedthat when the vehicle,

to which it is attached, is subjected to sutl.

den shocks, jolts and jars, fthe device will eectuelly' neutralisetheshock of the opn posing forces.

rihe invention consists in the features of construction and combinationof parte herein the thawing is shown side elevation oi this improvedshock Aabsorber applied or attacheci to e rear vehicle spring and vwheelaxle.

Referring to the drawing, to the vehicle or car ironie l is attached, inany suitable inanner, a vehicle spring 2 upon which is centrallymounted, by means ofbolts or retainers 3, thevupper outer end of ashockabsorber frame 1i, which is preferably formed oi an upper sect-ion5 ariel a lower section 6 hingeoi 'together et their inner meeting endsY. 'lllie lower frame section 6 is iiireoly secureol, by means of boltsor retainers 8, about the enti journal 9 of the vehicle axle, ani the,

outer end of this section is bent clown and outvvarrily, as shown, forthe purpose of receiving anu engaging an elongated post 10 which has itsupperend securedto theupper trarne section 5' enti its lower en securedthrough the lower frame section 6, an edQ justelole nut il engaging itslower threaded emi. This post l0 is encircled. by a coiled or 4 otherspring; l2 thus pror-Iiding means for producing the desired amount oiftension between the upper and lower shock absorber traine sections.

lt will notecl that the hingllfecl connection 7 prerentsbeclwarfi,forward, und side or 'lateral motion or increment ci the device.

Furthermore, the shoot: absorber ispositioiieolA so that its coiledspring lies centrally beneath the Vehicle spring for the purpose oifequally distributing and neutralizing the l:

shocks, rjars or jolts caused by the vehicle Wlieel'l contacting roughor uneven sur faces. l 4

in this construction no lubrication'is re quired, snol all ot the partsof the device are constructed-in a compact and durable man* ner and Witha View to compensating for and producing a vneutraliningeffect when the"vehicle is traveling over rough roads. The shock absorber traine ishingefifat its inner ends' and between` its 'opposite' outer ends ispositioned the spring" 12, thus providing a constructionfor dividingstress and strain at both ends or the device.

Without specifically lirniing myself to the ai'oresaici construction, lclaim:

l. in combination with a Vehicle spring, a shock absorber comprising anupper .section ancl a-lower sect-ion hinged, together at their inner`meeting ends, the upper section being secured to the central portion ofthe'vehicle spring, anti vthe lower section being securerl to a Wheelaxle, and an absorber spring positioned between and contact-ing both theupper 'ancllower hingelsections, substant-ially in alineinent with thecentral portion of the vehicle spring adjacent to the aide,substantially as (lescriberl.

2. in Vcombination with a Vehicle spring, a. shock ahsorbencoinprisingopposing; cour pleinental sections hingeti together at their meetingends, the outer end of the upper' section being secured to the vehiclespring, ancl the lower section being secured te a Wheel axle and itsouter end being adjacent to the axle and in parallel alimentent with.the upper section, e post spaced between and secured to said uppersection and relatively movable to the lower section, anti a springinterposecl'between seid upper and lower sections about. said post,substantially as described. I

3. in combination lwith e Vehicle spring, a. shock absorber, comprisinglopposing com pleinental 'sections hinge together et their meeting encls,the outer 'enel ofthe upper section being secured to the vehicle s, ing,and the lower section trains,r secured to e, wheel axle and its outerenel being adjacent l to the axle and in parallel' alnement with the uper section, a, post spaced between and secure to said upper section andrelatively movable to the lowersection, and a spring bi interposedbetween said upper and lower.

sections about said post, the spring being positioned in substantialalinement with the v central portion of the vehicle spring for equallydistributing the vibrations thereto, substantially as described. i
